Software development teams are often geographically distributed from their customers and
end users. This creates significant communication and coordination challenges that impact …

We present a new parallel computational model, named LogGPS, which captures
synchronization. The LogGPS model is an extension of the LogGP model, which abstracts …

Image registration is a technique for defining a geometric relationship between each point in
images. This paper presents a data distributed parallel algorithm that is capable of aligning …

This paper describes the evolution of the Portals message passing architecture and
programming interface from its initial development on tightly-coupled massively parallel …

This paper introduces a high performance communication middle layer, called PM2, for
hetero-geneous network environments. PM2 currently supports Myrinet, Ethernet, and SMP …

The polytope model has been used successfully as a tool for program analysis and
transformation in the field of automatic loop parallelization. However, for the final step of …

This paper introduces a version of MPICH handling efficiently different networks
simultaneously. The core of the implementation relies on a device called ch-mad which is …

Sort-last parallel rendering is a good rendering scheme on distributed memory
multiprocessors. This paper presents an improvement on the binary-swap (BS) method …

Dynamic programming has been one of the most efficient approaches to sequence analysis
and structure prediction in biology. However, their performance is limited due to the drastic …

ABSTRACT The RWC PC Cluster II, consisting of 128 Intel Pentium Pro microprocessors
connected by a Myricom Myrinet giga-bit network, achieves the comparable speed of a …
